The EmDrive has been dismissed as “impossible” on more than one occasion because it appears to violate Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction. But if a leaked NASA paper posted online last Saturday is to be believed, then not only are NASA scientists pursuing an EmDrive, but they actually made one that works.
As detailed in the paper, a team of NASA physicists led by Harold “Sonny” White and Paul March—both leading figures in exotic propulsion systems—was able to generate thrust in a “tapered RF test article” (read: EmDrive prototype) during a series of tests at NASA’s Eagleworks Labs at Johnson Space Center in the fall of 2015.
